Police said McCandless-Dietrich was driving the wrong way down a one-way section of Route 145 to Route 248 when he crashed into a vehicle driven by Zachary Wieder, 27, of Washington Township, Lehigh County, who died of multiple blunt force trauma.

Police said after the crash, they found an open bottle of vodka in McCandless-Dietrich's vehicle and his blood-alcohol content was 0.16 percent, twice the legal limit to drive in Pennsylvania. Other bottles of alcohol were found outside the vehicle, police said.

Police said Weider's passengers — Chelsea Sergeant, 24, of Allentown, and her child — had severe injuries, according to police.

The 4-year-old boy had a broken back, lacerated liver and broken arm, according to court records. Sergeant had "multiple major injuries" including a broken jaw, broken arm and shattered pelvis.

Police said McCandless-Dietrich and a passenger in his vehicle, Jocelyn Saul, 22, of Northampton, also were hurt.

McCandless-Dietrich said at his arraignment Thursday he had no prior criminal record and was working as a pipe fitter. He was sent to Northampton County Prison under $100,000 bail.

McCandless-Dietrich's attorney, Michael Moyer, said his client knew the charges were coming.

McCandless-Dietrich arrived at court Thursday hobbling behind a walker, with his foot in a cast. Moyer said McCandless-Dietrich recently underwent a medical procedure and still needs physical therapy for injuries he suffered in the crash.

Michael Jon McCandless-Dietrich, 23, of Danielsville surrendered Thursday to police on numerous charges stemming from a fatal December 2014 crash in Lehigh Township.

"This is a tough case and it's a real tragedy for everyone involved," Moyer said.
